Final answer:
Natural fibers usually come from plants, animals, or minerals, with plants providing fibers like cotton and linen from various plant parts, animals yielding fibers like wool and silk, and minerals offering fibers like asbestos.
Step-by-step explanation:
Natural fibers typically come from plants, animals, or minerals. Plant-based fibers, like cotton and flax (linen), are obtained from the seed hairs, stems, and leaves of plants. Animal fibers, such as wool and silk, are derived from the fur or secretions of animals. Mineral fibers, although less common, include materials like asbestos, which are directly sourced from certain minerals. Each type of fiber has specific properties and uses, influencing how they are harvested and processed. For instance, cotton comes from the fluff around the seeds of the cotton plant and is known for its softness and breathability, while silk, produced by silkworms, is valued for its smooth texture and luster.
